MFM will not connect/update

Hey all,

I tried to search this without any success. I apologize if it is a duplication.

I have not been able to connect with MFM for a couple weeks. I have been trying to disable by GO times because I no longer need my heater during the day. Without connection, I cannot track it and cannot remote start or lock/unlock the doors. Luckily, the car drives fine and still charges without a problem. I tried disconnecting the 12V to restart the system but it did not work. Have any of you experienced this, or have ideas? It is a 2015.

Thanks in advance.

Look in the owners manual for the Telematics fuse, pull it and reset it after a few minutes. If I remember correctly its in the fuse panel in the trunk.

My parents had to do this once with their C-Max Energi because it wouldn't connect to MFM. Pulling the TCU fuse fixed it.

Well, I pulled five different fuses I thought may have been close to a Telematics fuse without luck. There is not a Telematics fuse listed in my manual (2015). I did end up trying one in the front, two at the passenger compartment, and one in the trunk without luck.

When you say telematics fuse, do you know the way it is described in the manual? Thanks everyone, I really appreciate the assistance. I am trying to avoid a trip to the dealer for them to poke, prod, scrape, and mess up my perfect ride.

Ah! In your owners manual, found here:

Its called the "Cellphone Passport Module" Page 165 F1.

Thanks jmueller. That is one that I tried but maybe I did not have it out long enough. I will remove it again, start the car, and turn it off before I reinstall. I will try that again tonight. Thank you!

When we had the issue with the C-Max Energi we removed it for a few minutes but did not start the car with it removed.

Just curious. What cellular network does it work on? Verizon? AT&T? etc? Is the "phone number" to the car listed anywhere?

AT&T and it's the old technology that will soon no longer exist. There are other threads specifically about this issue.

Curious. If I recall correctly, the first 5 years of MFM are free.

If AT&T kills 2G on Jan 1, 2017 as they've stated, that definitely won't be 5 full years for me. Can the cell radio / modem in our cars be upgraded to 3G (or 4G)? Or, is one of the main reasons I got my car (remote starting) about to be dead in 1.5 years?
